No more swimming in shallow warm waters or at all in July, August and September when deeper water is warm.
No more motor-boating where people may enter the water, as that stirs up the sediment.
That’ll help reduce the risk.
That’ll go over like a lead balloon, like when they forbade people to play outside or go to the beach in 2020-2021. Just put your covid mask back on, that is, if you ever took it off, it will protect you from everything.
